Title: Productivity and nutrient uptake of soybean (Glycine max) as influenced by bio-inoculants and farmyard manure under rainfed conditions
Abstract: A field experiment was conducted at Wadura in Jammu & Kashmir during the rainy (kharif) season of 2004 and 2005 to study the efficiency of Rhizobium, Azotobacter, phosphate-solubilizing bacteria (PSB) and farmyard manure (FYM) on performance of rainfed soybean [Glycine max (L.) Merr.] and soil fertility. Results revealed that sole or dual inoculation of soybean with biofertilizers, application of FYM and recommended dose of fertilizer (RDF) significantly increased the plant growth, nodulation, seed and straw yields as well as N and K uptake over the control. Application of Rhizobium + Azotobacter + PSB + FYM showed significantly higher number and weight of nodules, but it was on par with that of Rhizobium + PSB + FYM and RDF. The improvement in seed yield over the control was 46.6, 42.2 and 38.8% under RDF, Rhizobium + Azotobacter + PSB + FYM and Rhizobium + PSB + FYM respectively. Further, inoculation of soybean with Rhizobium and PSB registered respectively 19.8 and 11.2% increase in grain yield over uninoculated control. Maximum N and P uptake, and available P were recorded with RDF, followed by Rhizobium + Azotobacter +PSB +FYM and Rhizobium + PSB + FYM, whereas the highest K uptake, organic C, and the available N and K were observed with Rhizobium + Azotobacter + PSB + FYM. Application of Rhizobium + Azotobacter + PSB + FYM increased the available soil N by 31.2 kg/ha and available P by 2.05 kg/ha over the initial level.
